BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to television technology, and moreparticularly to providing a television channel selection canvas.

2. Background Art

Sources of video signals available within a typical household haveproliferated, and are likely to continue to do so. Hundreds oftelevision channels are typically available through digital cable orsatellite television service. Moreover in a residence, a consumer mayalso have a personal video recorder (PVR), a security monitoring system,a video baby monitor, and/or a security monitoring system that produceadditional video signals.

Existing television channel guides and remote controls provide arelatively crude mechanism for previewing and choosing which televisionvideo signal to view, and do not support video signals from othersources, such as a security camera. For example, existing cable TVselection guides provide a listing of channels that can be viewed. Theseguides typically provide a scrolling list of channels that identify thechannel number and programming information (e.g., name of show, time,rating, etc.). In order to view what is playing on a particular channel,a user will usually have to wait for the guide to scroll through theentire list of channels. Even with basic cable services, where only50-100 channels are available, waiting for a channel of interest toappear can be tedious and frustrating. While digital cable and satelliteTV services allow a user to jump to a particular channel in a selectionguide, these guides remain limited in that they typically show only thechannel and title of the show. Upon selection of a particular channel, asummary description can be provided, or the video signal associated withthe channel can be displayed.

Some higher end television sets can display a picture in a picture (PIP)as a way of previewing a channel. PIP systems are limited, however, inthat they typically show only one alternative channel and can not beconfigured to a particular user. Furthermore PIP displays on atelevision typically provide limited previewing and selectioncapabilities. As a result consumers have not widely embraced PIP.

Historically, selection guides and channel previewing mechanisms havebeen limited by the processing power and analog nature of televisionsets and cable set top boxes. Increasingly television signals are beingtransmitted digitally, and televisions and set top boxes have increasingprocessing power and ability to manipulate signals. Other technologyadvances have stimulated the deployment of other sources of videosignals, such as security cameras and video phones. Finally,alternatives to distributing video signals throughout a residence arebeginning to emerge. These alternatives can be used to form anintegrated in-house network for all video sources. While thesetechnologies are developing, previewing, integration and selectioncapabilities for video signals have lagged behind, and remain relativelyprimitive. Current video previewing and selection mechanisms do not takefull advantage of the migration to digital technologies and the addedprocessing power in televisions and set top boxes.

What is needed is a system that provides a user interface mechanism forallowing a user to conveniently preview video signals and select a videoto be viewed.

Those skilled inthe art with access to the teachings provided herein will recognizeadditional modifications, applications, and embodiments within the scopethereof and additional fields in which the present invention would be ofsignificant utility.

In particular, for ease of illustration, invention embodiments areprimarily discussed in the context of a residential setting. Theinvention is not limited to use in a residential setting. The inventioncould be used in any setting where multiple video signals are present,such as an office or other business location. Furthermore, the inventionembodiments focus on displaying the channel selection canvas on atelevision. The invention is not limited to use on a television. Thechannel selection canvas could be displayed on any display devicescapable of displaying multiple video streams or snapshots. Such devicescould include, but are not limited to a display monitor, laptopcomputer, personal computer, personal digital assistant (PDA), cellphone, or a smart phone.

FIG. 1 is a diagram of channel selection canvas 100, according to anembodiment of the invention. Channel selection canvas 100 can bedisplayed on a video display device for allowing users to preview andselect video signals to watch. The video display device could be anytype of display device capable of displaying multiple video thumbnails,such as a cathode ray tube (CRT), liquid crystal display (LCD), plasmaflat panel display (FPD), and the like. Video thumbnails can includefull motion video, slow motion video, and snapshots of a sampled videostream. The display devices could include, but are not limited to,televisions, monitors, personal computers, laptop computers, personalcomputers, PDAs, cell phones, smart phones, video phones and the like.

Channel selection canvas 100 includes header field 110; channelselection field 120; a set of optional video selection fields 130A, 130Band 130C; video phone field 140; news streaming field 150 andadvertisement field 160.

The fields are oriented within channel selection canvas 100, such thatheader field 110 appears across the top of channel selection canvas 100.Channel selection field 120 is located on the left half of channelselection canvas 100 beneath header field 110, while the optionalselection video fields 130 and video phone field 140 are located on theright half of channel selection canvas 100. News streaming field 150 andadvertisement field 160 are located across the bottom of channelselection canvas 100.

Alternative embodiments of channel selection canvas 100 can include anycombination of these fields, including but not limited to containingonly channel selection field 120. In other alternative embodiments theorientation of the fields can be different. In one embodiment thespecific orientation of the fields can be dynamically determined by auser. In this case, the user can include those fields that are of mostinterest to him and adjust the location, size, color, theme, background,and orientation of the fields to meet his personal preferences.

Header field 110 displays general information. General information canidentify the user of the canvas. The general information can alsoinclude the date, day of week, time, weather information, and the like.

Channel selection field 120 displays a set of television channel videothumbnails for previewing and selecting programming channels (e.g.,broadcast television, cable television, satellite television channels)to watch. A video thumbnail can be full motion video, slow motion video,snapshots of the video signals that refresh periodically, or snapshotsthat do not refresh. The number of television channels displayed will bea function of the capabilities of the video receiving device (e.g.,television or set top box), the capabilities of the display device andvideo quality desired.

Historically, when analog signals were used exclusively a tuner wasrequired for every channel to be viewed. Currently, with digitaltechnology a tuner is not needed for every channel, thus as more digitaltelevision sets and digital services become available displayingmultiple thumbnails can occur without the expense of multiple tuners.

In one embodiment, a video thumbnail, the name of the show, the time forthe show, the network and picture quality (e.g., standard definition orhigh definition) can be displayed for each channel being previewed. Auser can select to view one of the channels within channel selectionfield 120. Selection mechanisms can include scrolling over the selectionof interest, use of an RF or infra-red remote, or other mechanism thatwill be known to individuals skilled in the relevant arts. Theseselection mechanisms apply to all fields within channel selection canvas100.

Optional video selection fields 130 can be used for displaying ancillaryvideo thumbnails. Optional video selection fields can include securitymonitor video thumbnails, baby monitor thumbnails, personal videorecorder (PVR) thumbnails or any other type of video signals. When usedwith a PVR, the optional video selection field can be used to stepthrough the recording segments on a PVR to find a particular recordingof interest.

Video phone field 140 can be used for displaying a video phone thumbnailthat shows a party being communicated with over a video phone. The videophone field can also be programmed to allow a user to answer or place acall through the channel selection canvas.

News streaming field 150 can be used to display streaming newsinformation. In one embodiment the streaming news information caninclude news headlines such as those streaming along the bottom of a CNNbroadcast. In another embodiment, the streaming news information caninclude stock ticker symbols such as those streaming along the bottom ofa CNBC broadcast.

Advertisement field 160 can be used to display a video advertisementthumbnail. In one embodiment, a channel selection canvas generator suchas is discussed with respect to FIG. 4 could be used to monitoradvertisements on a particular channel for display while an end user wasviewing the channel selection canvas. For example, if a user selectedESPN as one of the channels that he wanted to include in his channelselection field, a channel selection canvas generator could store asmall set of video advertisements appearing on that channel and thenplay those ads in advertisement field 160 when channel selection canvas100 was used. In this way, the ads are more likely to be of interest tothe user. Alternatively, further customization could occur such thatbased on user preferences and header information within anadvertisement, ads targeted to a user profile are displayed inadvertisement field 160.

FIG. 2A is a diagram of channel selection canvas 200 emphasizing thechannel selection field, according to an embodiment of the invention.Channel selection canvas 200 represents a simple embodiment of channelselection canvas 100 in that it includes only header field 210 andchannel selection field 220. Header field 210 identifies that channelselection canvas 200 has been customized to a user named Mike. In thisembodiment, channel selection field 220 has been customized to displayfive channels of most interest to the user. In other embodiments, thenumber of display channels could be more or less. For example, anindividual may wish to display 10, 15 or even 50 video thumbnails. Theupper bound for the number of thumbnails will be a function of theprocessing power of the video processing device, the size of the displaydevice and the practical consideration of how many thumbnails a user canreasonably view.

The five video thumbnails shown include Channel 2-NBC, West Wing;Channel 24 ESPN, Playmakers; Channel 48-CNN, Headline News; Channel99-CNBC, Power Lunch; and Channel 150, HBO-Star Wars. Channel selectionfield 220 also includes icon 226 identifying that the show Playmakers isavailable in high definition. Also included within channel selectionfield 220 is scroll bar 228 that can be used to allow a user to scrollthrough other channels not among his favorite channels for display.

Channel selection canvas 200 can be used in a number of ways. In oneexample, the user's preferences for channel selection canvas 200 can bestored in either the video display device or in another interconnecteddevice. User preferences can also have a time of day or locationcomponent. For example, a user may have three pre-set channel selectioncanvases, such that if he turns on the television in the morning achannel selection canvas may come up that shows User Mike's favoritemorning TV channels—perhaps the NBC, CNN and CNBC. Alternatively if UserMike turns on the television during the mid-day, a channel selectioncanvas may come up that shows his favorite channels for afternoon soapoperas, talk shows or cartoons, such as NBC, CSPAN and Nickelodeon. And,finally channel selection canvas 200 can come up if he turns on the TVin the evening. In one embodiment, channel selection canvas 200 can comeup on the television set in which a user intends to view the show.

In another embodiment, a user may be at home and the home includes awireless network. A user may be working in his study, and wants glimpseswhat is on television. Channel selection canvas 200 could appear on hispersonal computer or laptop. In this case, it may be more likely thatthe video thumbnails are slow motion video or refreshed snapshots. Inthis case, video selection canvas 200 is being used to previewselections. In another example, a user may have a wireless PDA. The usermay request the channel selection canvas on the PDA, and then wirelesslytransmit a request from the PDA to a television to turn the televisionon and display the channel of interest.

FIG. 2B is a diagram of a channel selection canvas 230 emphasizing theintegration of video signals from multiple sources, according to anembodiment of the invention. As in the case of channel selection canvas100, channel selection canvas 230 includes a header field; channelselection field; a set of optional video selection fields; video phonefield; news streaming field and advertisement field.

Channel selection canvas 230 includes header field 232, which identifiesthat the canvas is Mike's Canvas. Header field 232 also provides thedate, time, and current weather conditions. Channel selection field 240includes the same channel selection information described with respectto channel selection field 220 in FIG. 2A. Channel selection canvas 230,however, includes optional video selection fields 250 and 260, and videophone field 270.

Optional video selection field 250 shows an implementation in whichsecurity camera thumbnails can be previewed. In this embodiment, thelocation of the security camera is given, along with a scrollingmechanism for the case when a user may have multiple security cameras.Optional video selection field 260 shows an implementation in which babymonitor thumbnails can be previewed.
